A particular solute is dissolved in a solvent resulting in a solution that is 54.0 % solute by mass. If the molar mass of the solute is 178.10 g/mol, what is the molality of the solution? (Assume the solute is a nonelectrolyte).
Why can measuring osmotic pressure help you find the molar mass of a solute? Assume that the solute is not an electrolyte. Choose the best answer. Choose one: Osmotic pressure depends on the hydrogen bonding capacity of the solute. Osmotic pressure depends on the molarity of the solute. Osmotic pressure depends on the mass of the solute. Osmotic pressure depends on the chemical identity of the solute. The osmotic pressure inside human cells is about 8 atm. at 20.85 °C. My advisor once misread a protocol I gave him, and without thinking washed the cells with a solution of 1.88 M NaCl. He immediately swore. What happened to the cells? Choose one: O The cells absorbed water and exploded. The high concentration of salt made the water boil at room temperature. The high concentration of salt made the water freeze at room temperature. The cells lost their water to the solution and collapsed.
